Wilson cuts rectangular mats for picture frames. The area of the mat before it is cut is represented by the function M(x) = 4.5x2 + 17x + 16. The area that is cut out and removed from the middle of the mat is represented by the function
M(x) = x2 + 6x.
If x is the width of the portion of the mat that is cut out, which function best describes A(x), the area of the cut mat?
OA A(X) = 5.5x2 + 23x + 16
OB. A(x) = 3.5x2 + 11x + 16
O C.
A(x) = 4.4x2 + 17x + 10
OD. A(x) = 4.5x2 + 16x + 10

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
